Cautions for ensuring the projector’s performance

• Do not install in places subject to vibrations or shocks.

If installed in places where the vibrations from power sources and the like are conveyed, or in

vehicles or on vessels, etc. the projector could be aected by vibrations or shocks that may dam-

age internal parts and lead to malfunction.

Install in a place not subject to vibrations or shocks.

• Do not install near high voltage power lines or power sources.

The projector may be aected by interference if it is installed near a high voltage power line or

a power source.

• Do not install or store in such places as those described below. Doing so could lead to malfunc-

tion.

- Places where strong magnetic elds are generated

- Places where corrosive gases are generated

• If intense light like laser beams enters from the lens, it could lead to malfunction.

• Consult your dealer before using in places where much cigarette smoke or dust is present.

• When the same still image is projected for a long period of time with a computer, etc. the pattern

of the image may remain on the screen after the projection is stopped, but it will disappear after

a while. This happens due to the properties of liquid crystal panels, and is not a malfunction. We

recommend using a screensaver on the computer side.

• When using the projector at altitudes of about 5500 feet/1600 meters or higher, be sure to set

the [FAN MODE] to [HIGH ALTITUDE]. If not, the inside of the projector may get hot, leading to

malfunction.

• When the projector is used at high altitudes (places where the atmospheric pressure is low), it

may be necessary to replace the optical parts (light source, etc.) sooner than usual.

• About moving the projector

- Be sure to mount the included lens cap to protect the lens from scratches.

- Do not subject the projector to vibrations or strong shocks.

The projector could be damaged otherwise.

• Do not use the tilt feet for purposes other than adjusting the projector’s tilt.

Improper handling, such as carrying the projector by the tilt feet or using it leaned against a wall,

could lead to malfunction.

• Do not touch the surface of the projection lens with bare hands.

Fingerprints or dirt on the surface of the projection lens will be enlarged and projected on the

screen. Do not touch the surface of the projection lens.

• Do not unplug the power cord from the projector or the power outlet while projecting. Doing so

could cause deterioration of the projector’s AC IN terminal or power plug contact. To interrupt

the AC power supply while images are being projected, use a breaker, etc.

• About handling of the remote control

- The remote control will not work if the projector’s remote signal sensor or the remote control’s

signal transmitter is exposed to strong light or if there are obstacles between them that obstruct

the signals.

- Operate the remote control from within 7 meters from the projector, pointing it at the projec-

tor’s remote signal sensor.

- Do not drop the remote control or handle it improperly.

- Do not let water or other liquids get on the remote control. Should the remote control get wet,

wipe it o immediately.

- Avoid using in hot and humid places as far as possible.

- When planning not to use the remote control for long periods of time, remove both batteries.

Important Information

xviii

• Take measures to prevent external light from shining on the screen.

Make sure only the light from the projector shines on the screen. The less external light on the

screen, the higher the contrast and the more beautiful the images.

• About screens

Images will not be clear if there is dirt, scratches, discoloration, etc. on your screen. Handle the

screen with care, protecting it from volatile substances, scratches and dirt.

Clearance for Installing the Projector
